Everything else should be in checkers.metaquals.

Until the commented-imports feature is done, copying over both
checkers.quals and checkers.metaquals should work.

However, I don't know about the RELEASE_7 error -- InternedChecker has
had that since it was written, so I can't think of why you'd be
getting that error now if you haven't been getting that all along.
